SPECIFICATION forming part of Letters Patent No. 642,372, dated January 30, 1900.

Application tiled April 1, 1898. Serial No. 676,144. (No model.)

To all whom t may concern:

Beit known that we, CHARLES L. SAFFORD and OscAR E. PELTZER, of Chicago, in the county of Cook and State of Illinois, have invented certain neuT and useful Improvements in Hand-Stamps; and we do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings, and to the letters of reference marked thereon, which form a part of this specification.

This invention relates to improvements in hand-stamps, and refers more particularly to that class of stamps, such as dating-stamps, which are provided With one or more sets of permanent types or dies and one or more sets of movable types, Which latter are adapted to be shifted or moved to provide different combinations of said movable types.

A hand-stamp embodying our invention consists generally of a type-base provided with movable or shiftable types and adapted to support said type at the printing-point and a die-plate provided with one or more sets of permanent type, which is so located with reference to the type-base that an impression is made simultaneously from both the permanent and movable types.

Our invention consists in so constructing and arranging the parts of the stamp that the type-base and die-plate are movable with relation to each other, so that in adjusting the parts for operation or when either of the permanent or movable types become Worn the part to which said types are attached may be moved with respect to the other to bring the printing-surfaces of said type exactly in the same plane.

The invention consists in the matters herein set forth, and more particularly pointed out in the appended claims.

Figure lis a front elevation of one form of hand-stamp constructed in accordance with our invention. Fig. 2 is a side elevation thereof. Fig. 3 is a vertical section taken on line 3 3 of Fig. 2. Fig. t is a front elevation of another form of stamp, in which the types are adapted to be removably secured in the type-y base. Fig. 5 is a side elevation thereof. Fig. 6 is a vertical section taken on line 6 6 of Fig. 5. Fig. 7 is a front elevation of a modified form of stamp. Fig. 8 is a side elevation thereof. Fig. '9 is a bottgm plan View of the same. Fig. l0 is a fragmentary side elevation thereof. Fig. 11 is a cross-section taken on in said figures, A designates the frame of the stamp; B, the handle thereof; C, a type-base attached to said frame, and D a die-plate, also attached to said frame by means permitting relative movement between the same and the type-base. E designates independentlymovable type-bands carrying types E', arranged to engage the type-base C and to be shifted thereon to afford the various combinations desired-as, for instance, to give a series of numbers or to print successive dates. Said frame A consists of parallel side plates A A and a transverse connecting-plate A2, attached'to or formed integral With said side plates. Said side plates and end plate Will preferably be made from a single piece of sheet metal and formed by a suitable swaging operation. The type-base C consists of a rigid bar, which is attached in any suitable manner, as by soldering or brazing, at its opposite ends to the free ends of the side plates A', and is constructed to support the movable types at the printing-point, being made of a Width equal to or slightly greater than the Width of the type. The type-base in the construction shown is made stationary, While the die-plate is movably connected With the frame, to Which the type-base is rigidly attached. Said die-plate D is provided with parallel arms or Iianges D', which overlap the outer ends of the plates IOO ' face with sockets to receive the movable type with the plates, and thereby hold said die in operative relation to the type-base. The dieplate D is herein shown as provided with two sets of permanent types or dies'DZ, arranged on opposite sides of the movable types E, and said die-plate is therefore convenientlymade of a single piece of sheet metal and provided with a longitudinal slot D3, through which the movable types project when the die-plate is in position upon the frame, so as to bring the movable and permanent type in the same plane. The ends of the side members A' of the frame will desirably project through said slot and engage the sides thereof to afford interlocking connection between said frame and plate, which will serve to prevent said plate from turning or swinging on the frame. The type-bands E, which carry the movable types, are trained about the type-base at one end of the frame and engage at the opposite end of the frame rotative wheels F, by which said bands are actuated to move the types with relation to the type-base C. Said wheels are rotatively mounted on a shaft F', which is att-ached rigidly at its opposite ends in the opposite side plates A of the frame. Said wheels F are each provided on one side thereof with a radially-extending [lange f, which forms a guide by which the band engaging the same is held in place upon the wheel. Said flanges are conveniently knul-led or serrated to form engaging surfaces bywhich the wheels may be turned by the thumb and finger to move the bands engaged thereby. The typebase C is provided between the type-bands with separating devices or guides conveniently consisting of loops of wire which encircle the same and which serve to maintain the type-bauds in proper relation with each other.

In Figs. et, 5, and 6 is shown a modified form of stamp in which the separate types are removably secured in the base instead of being mounted on shifting bands, as in the construction described, so that when a new combination of movable types is desired said types may be removed from the base and other types substituted in their place. As shown in said figures, H designates the frame of the stamp, I the handle thereof, and J the dieplate, which is movably mounted upon said frame. Said frame l-I will preferably consist of a solid casting of suitable form, which is provided with a screwh,by which it is attached to the handle, and is provided in its outer K, said outer face of the frame in -this instance constituting the type-base of the stamp. The die-plate J is provided with parallel arms or flanges J, which overlap the outer opposite faces of the body portion H of the frame and are secured thereto by means permitting relative movement between said parts. Said flanges are provided with longitudinal slotsj, through which pass clam ping-screwsj, which latter have screw-threaded engagement with the apertures or sockets in the frame H.

the movable types K, and the die-plate is therefore provided between said permanent types with a longitudinal slot through which the movable types project when the die-plate is in position upon the stamp-frame.

With the construction described it will be obvious that in first adjusting the stamp for use or when eithenthe permanent or movable types have become worn, so that their faces are not in the same plane, it will only be necessary to loosen the clam ping-screws and move the die-plate in the direction required to bring the several sets of type accurately in proper position for printing. Ordinarily the types mounted upon the die-plate will be first worn away by reason of the fact that said types are in constant use,while the movable type are used intermittingly only, so that the adj ustment referred to will usually be accomplished by moving the die-plate inwardly with refererence to the type-base. Obviously the arrangement of the parts described may be reversed, the die-plate being made a stationary part of the stam p, while the type-base and the parts connected therewith may be constructed so as to be removed and the adjustment between the said parts effected by moving the type-base.

Hand-stam ps of the character described may be used for various purposes-such, for instance, as for dating-stamps in which the permanent types carried by the die-plate will constitute words to indicate the character of the stamp, as a receiving-stamp or the like, while the movable types will bear suitable ligures and letters to indicate the date on which the impression is made. Said stamps are also suitable for use in applying serial numbers to documentsw-sucli as orders, claims, and the likein connection with words or igures which indicate the character of the document.

As a further and separate improvement we have shown in Figs. 7 to l1, inclusive, a form of stamp in which the die-plate'is adapted to be temporarily moved away from the typebase, so that the characters which engage said type-base lnay be used separately from the characters on the die-plate. This result is conveniently accomplished by making the die-plate proper separate from the attaching plates or flanges of the previously-described constructions, hinging the same at one end to one of said plates and detachably locking the same to the other plate. As shown in said Iigures, M designates the die-plate, and N N the plates or flanges by which it is detachably and adjustably connected with the side members A' A of the frame of the stamp by means of attaching-screws a. Said die-plate is made separate from the attaching plates and is hinged at one end to the plate N in such 1nanner that it may be swung away from the typcbase C in the manner shown in Fig. l, so that roo IIO

an impression may be made from the characters of the type-base alone. For this purpose the attaching-plate N is provided With a laterally-projecting part or lug N2 and the dieplate is provided with overlapping parts or lugs M, which are connected with the lug N2 by a pivot-pin M2. The parts of said hinge are made of su fcient length to permit the dieplate to assume a parallel relation with respect to the side members of the stamp when swung away from the type-base before coming in contact therewith, so that said dieplate may be conveniently held in its retracted position by the same hand of the user which manipulates the stamp, s0 that the otherhand may be fr'ee to be used for other purposes. Any suitable means may be employed for detachably connecting the opposite end of the4 die-plate with the attaching plate or flange N. Said means consists in lthe present instance of a spring-latch O, attached to an overlapping part or fiange M3 on said die-plate and provided with an inwardly-projecting detent o, adapted to engage a suitable recess or socket in the plate or flange N. In the present instance said detent engages the slot n of said plate, through which the holding-screw a passes, said slot being made of slightly-increased length, so that the latch Will not interfere with the adjustment of the holdingscrew therein. The latch is provided with a finger-piece o', by means of which it may be conveniently manipulated. The construction described permits the die-plate to be swung away from the type-base without releasing the attaching-screws a, and therefore Without disturbing the adjustment between said parts.

As a separate improvement and as a means for insuring a rigid engagement between the .attaching plates or lianges of the die-plate and the side members of the stamp, we have shown in Figs. 8 to 11 said flanges and side members as provided with interlocking recesses and projections. Said recesses and projections, as shown at 'n in Fig. l1, are arranged longitudinally of said side members,

and serve also as guides in the movement of the die-plate upon the frame to prevent lateral displacement of said plate.

We claim as our inventionl. A hand-stamp comprising a frame having parallel side plates, a type-base attached rigidly thereto, movable types engaging said base, a die-plate provided with iianges having sliding engagement with said side plates of the frame, and means for securing said dieplate rigidly to said frame.

2. A hand-stamp consisting of a frame having parallel side plates, a type-base attached rigidly to said plates, movable types engaging said base, a die-plate having permanent types and provided with flanges which have sliding engagement with said side plates of the frame and provided also with slots engaged by clamping-screws which have screwthreaded connection with said side plates of the frame.

3. A hand-stamp comprising a frame having parallel side plates, a type-base attached rigidly thereto, a die plate provided with flanges having sliding engagement with said side plates of the frame, interlocking recesses and projections on the contacting faces of the plates and flanges, and means for clamping the same together.

4. A hand-stamp comprising a frame having parallel side plates, a type-base attached rigidly thereto, a die plate provided with iianges having sliding engagement with said side plates of the frame, interlocking recesses and projections on the contacting faces of the plates and flanges arranged longitudinally of the plates, and means for clamping said plates and flanges together. y
